摘要 肺动脉高压(Pulmonary arterial hypertension,PAH)是一种由多因素引起的肺血管功能及结构异常,导致肺血管阻力增加,引起肺动脉压异常升高的临床综合征,严重时引起右心衰甚至死亡[1-3]。尽管目前临床上肺动脉高压诊断及治疗策略越来越多,但其预后仍旧较差。有流行病学资料显示特发性及遗传性PAH患者在经过常规治疗后,5年生存率仅为20.8%[4]。国内外研究提示微小RNA(microRNA/miRNA)可与其靶mRNA 3'端非编码区(3′-Untranslated Regions,3′-UTR)特异性结合,引起靶mRNA翻译抑制或降解,在细胞的生长、分化等过程中发挥重要作用。研究发现miRNA在PAH的发生、发展中起重要作用,因此识别PAH发病相关的miRNA及其作用靶点有望为PAH诊治提供新的途径。本文就miRNAs在PAH的发病机制及诊治方面的研究进展作一综述,并探讨其在PAH诊断、治疗方面的应用前景。
